Design Example for a Rectangular Concrete Tank : PCA Design Method
University of Colorado, Boulder
Spring Semester 2008
Prepared by Ben Blackard
The Portland Cement Association (PCA) has publications for designing rectangular and circular tanks. Some of the design provisions differ from that of the American Concrete Institute (ACI) specifications. Many in the industry use these PCA design concepts, so we will adapt them for our calculations as well. Much of the PCA publication is comprised of tables of coefficients for calculating moment and shear in two-way slabs. These tables should simplify the calculations. We will refer to the PCA Rectangular Concrete Tanks design manual as PCA-R, and the circular tank design manual as PCA-C.
